Could not access Logitech Mediaserver through iPeng or the webpage interface. First I suspected firewall rules in my lan, but no they were not to blame. Nor was it a problem with portforwarding in my router. The reason for the problem waas that my Ubuntu Server partition had run out of disk space. Luckily that could be solved by reprtitioning the partition sizes. The disk operations went smoothly and now I’m again able to stream music.
